BOX-TRANSFERRING MECHANISM FOR BOX OR PACKAGE TRANSMISSION MACHINES.

Original application filed November V5, 1915, Serial No. 59,860. i Divided and this application filed. September To all 'whom it may concern: j

Be it known that we, MELviLLE E. PETERS,

GEORGE H. FATH, and ALBERT F. MILLER,

citizens of the United States of America, residing at the city and countyof Denver and State of Colorado, have invented a new and useful YBox-Transferring Mechanism for Box or Package `Transmission Machines, of which the following is a specilication.

Our 'invention relates to a box transferring mechanism for boxes; and the object of our invention is to provide a box transferring mechanism for box wrapping machines in particularand for use on or in connection with mechanism where boxes or packages or articles of merchandise that can be handled by it are to be transferred from a receiving point or station toa delivery point or station, and then picked up at the delivery point or station and discharged or `moved away fromit for further treatment. j

We attain these results by the mechanism i illustrated inthe accompanying drawings,

in which: j

Figure 1 is a vertical longitudinal sectional view through a portion of a box wrapping machine, showing the improved box transferring mechanism and the operating means therefor.

' Fig. 2 isa transverse vertical sectional vievvfenlarged-on the line 2-2 of Fig; 1.

Fig. Bis a plan view of one of the box j i base .plate ofthe machine illustrating more fully the mechanism for operating the bar, which depresses the box grippers. j

Similar letters of referencerefer to! similar parts throughout the several views. j

Referring tothe drawings, v A `,The numeral 1 designates a box shaped frame having a table top portion that is provided with a receiving station and a delivery station or position. Through the longitudinal center of the table, a slot is formed, below. which is supported a slidewav 3, in which box grippers `4 and I5` are rleciprocally mounted.

` A spur gear isloosely mountedon a cross shaft 7 thatextends across and'is secured in.

bearings inthe sides of the table. The spur gear projects up into a slot 8 and meshes with a toothed `rack bar 9 which we term the box shifter rack, andwhich is mounted in the slidewa7 3. pinion .gear 10 rigidly securcdthereto in any suitable manner, and this pinion meshes with a toothed bar 11, the lower end of which is bolted to a forked lever 12, which straddles the main shaft 13, and is provided with a roller 13A which enters a suitable cam groove in a cam disk 14, which is mounted on the main shaft. The upper end of the toothed bar passes through a guideway 15, which is rigidly secured to the shaft 7. The box shifting rack bar is provided with a centrally projecting flange 16 which extends throughout its full length. This box shifting rack is held in the slideway 3 by caps 17 which are screwed to the top edges of the slideway. To the flange above thesecaps two clips 18 are secured, that project above the flange and form bearings for the opposite ends of a right and left hand threaded rod 19. Upon the opposite ends of the threaded rod 19, blocksQO are threaded, the upper ends of which are bifurcated to receive the lower ends of the gripping arms 4, which are rigidly mounted upon pins 21, which are pivotally mounted in the bifurcated ends of the said blocks, their ends extending beyond the sides of the blocks. Upon one end of each of the pins Qlis rigidly mounted an arm 22, the arms extending in opposite directions, and upon the outer end of each arm is mounted a roller 23. Upon the opposite end of each pin is secured a nut or washer 24C, and a coil spring 25 is mounted on the pin between the nut and the block 20, one end of which enters 'a hole in the nut and its other end enters -a hole in the block, these springs being under tension4 which is exerted to raise the armso that their outer ends, which are upturned, will extend a slight distance above the plane of the table. rlhe lower ends of the blocksZO are `also bifurcated, and are slidably mountedon the flange 16 of the rack bar 9.

j These box gripping arms l have their upper ends arranged to stand rertically upright when at the limit of their upward movement, and these upper ends are adapt- Specicaton of Letters Patent. j Patented Sept.. lill, 19117.,

rlhe gear wheel 6 has a ed to against and. grip`the"`opposite Wrench by means of which the threaded rod longitudinal bar may be turned and the blocks 2O nmovedto- Ward or away from each other to grip any size boX from the smallest to the largest; as illustrated, they are shown arranged to grip a large sized box. These box grippers are moved down out of the Way of each boxlas they deliver it to the delivery station by a 26, the upper edge of which Y terminates in a horizontal lip 27, ivhicliat all times engages the rollers 23' on theiarms v22. The opposite ends of the bar 2 6 are pivotally attached to levers 2S` and 29 respectively, the opposite end of the lever-29 .boing loosely mounted onV arod 30, Which extends transversely across thetable and is mounted in theV bearings in oppositesides of theframef The lever 28 is mounted mid- Way of its length upon a stationaryshaft `31, which extends` transverselyacross the table and issupported in the sides thereof. l

rlhe opposite end of this .lever 28Ais pivotally attached to one end ofa connecting rod 32,` the opposite end of which is pivotally connected toy a lever 33,1ivhich is mountedmidvvay ofits length` upon a stationary shaft 34, also supported inthe side frames ofrthernachine. rPheopposite end of the leverBS carries a` roller 35, which is engaged by` a cam 36 on the circumferential edge of -a dislr, which isl rigidly mounted on a shaft 3S; Whichis supported in bearings in the side frames ofthe machine. Theroller Y is; held against the edge ofthe cam disk bv a 1 Wheel 40, which meshesivith a similar coil spring 3.9, .which surrounds the shaft Si and is attached 'at one end to the lever 33 andV atthe other end to .a collar on the said shaftA The shaft ,3Sl carries a bevel gear gear Zl10n the adjacent end of the main shaftl.

As the disk 37 rotates, the cam 3G engages the roller 35, thereby rocking the lever 38, by which` the rod 32 is drawn upon and the vlever 28 rocked, ,its upper end being raised together With the upper endl of the lever 29,

Awhich.moves Ein unison with thelever-28,

thereto an upright i-2, which is similar to the blocks 20, and this upright supports the box discha'igingarm 5, rifidly .mounted ona pin which passes through. theupright and carries at oneV end, an 4arm .43 similar to the arms 22, and which is also provided With a roller similar to therollers 23on1tlie arms 22. The arm 43 is also actuated in one direction by a spring similarin all respects to the springs 25, \vhich raiseY the arms 22.

.The roller carried by the arinl is in continuous engagement With the lip Vof the bar 26, and the discharging-,arm ois, therefore, actuated simultaneously with the gripper' arms 4,. ,Y .l d d 'L l 's ltivill thusbe seen that at each-rearward movement of the rack bar raber: is transferred from` thereceivingpointor position to its delivery position by thegrippers .Il and the which `was in the delivery-position is caught by the varm 5 fromthe machine. i
